American IT Solutions Provider for Italian Office

Hello,
I'm looking for an American or British IT Solutions Provider that has an Italian presence for a Roman branch office of an American organization.
We need a network evaluation, diagramming, and proposal for several infrastructure upgrades. The proposal needs to be articulated according to an American business model... with a network map, product proposals and documentation articulating features and system integration.
We would hope to implement a solution toward the beginning of the next FY. If you have any suggestions in this area, that be greatly appreciated.
